ORNAMENTAL CHAIN-LINK.

SPECIFICATION forming part of Letters Patent No. 341,580, dated May 11,1886.

Application filed Ootoberl, 1885. Serial No.178.687. (No model.)

To all whom it WMI/y concern.-

Be it known that I, HENRY H. KELLY, of Attleborough Falls, in the countyof Bristol and State of Massachusetts, have invented certain new anduseful Improvements in Ornamental Chain-Links, of which the following isa specification.

This invention relates to an ornamental chain-link of that class knownas stretcherlinks, by means ofwhich achain inade ofsuch links canbeextended to acertain degree without breaking or tearing the garments.

In the accompanying drawings, Figure 1 represents aside elevation of myimproved ornamental chainlink; Figs. 2 and 3 are vertical longitudinalsections of the link, showingit respectively in contracted and extendedstate. Fig. 4 is a vertical transverse section of the same on line x m,Fig. 1; and Figs. 5, G, and 7 are different modifications of thelink.

Similar letters of reference indicate corre sponding parts.

Referring to the drawings, A represents a spiral spring or springs, theends of which are 2 5 soldered or otherwise attached to disks a. Thedisks (1 a are again attached to the interior of ornamental heads B B,which are provided with eyes I) b, by which the connection with theadjoining links of the chain is made. The heads B B are connected by anextensible stay, O, that is formed of two parts, d d, which arerespectively attached to the disks a a, the inner end of one part, d,being guided in a spirally or other shaped eye, (1", of the part (1 whenthe link is extended and stopped by an eye, (P, or other enlargement ofthe part cl when the stay is extended to it's full extent. The stay Ocontrols the extension of the spiral spring, and prevents the stretchingof the same 0 to such an extent that its tension is destroyed. Anornamental tubular sleeve or box, D, made of one or more parts and longenough to extend from one head to the other, incloses the spiral springA and protects the spring 5 against wear. The heads B B are of largerdiameter than the interior of the sleeve D,and abut against the ends ofthe box D by the action of the spring A, which latter may be extendedand bent to some extent over the ends of the box without being injured,whereby a greater flexibility and durability of the link is obtained.

The stay 0 is preferably arranged at theinterior of the spiral spring A,as shown in Fig.

2, or two or more spiral springs may be arranged with one intermediatestay O, as shown in Fig. 5, or two stays may be arranged outside of thespring, as shown in Fig. (i, or the spiral spring may be arranged in abox attached to one of the heads, while a second box is attached to theother head, said sleeves or boxes being adapted to telescope one intothe other, as shown in Fig. 7, whereby the spiral spring is entirelyinclosed.

The covering sleeve or box D may be made of any desired form or shape,plain, or ornamental, and forms with the spring, heads, and stay anextensible or so called stretcherlink, that gives to acertain extentwhen strain is exerted thereon, so as to prevent the breaking ofthe'chain or the tearing of the garment to which the chain is applied.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of an elongated tubular sleeve, aspiral spring inclosed by said sleeve and extensible beyond the endsthereof, heads of larger diameter than the interior of said sleeve,attached to opposite ends ofsaid spring and adapted to close against theouter ends of said sleeve when said spring is contracted, and anextensible stay connected to said heads, substantially as described.

' 2. The combination of an elongated tubular sleeve, a spiral springinclosed by said sleeve and extensible beyond the ends thereof, headsof'larger diameter than the interior of said sleeve,attached to oppositeends of said spring and adapted to close against the outer ends of saidsleeve when said spring is contracted, 0 said heads being provided witheyes at their outer ends adapted for connection with chainlinks, and anextensible stay connected to said heads, substantially as described.

3. The combination of an elongated tubular 5 sleeve, a spiral springinclosed by said sleeve, hollow heads of larger diameter than theinterior of said sleeve to close the outer ends thereof, disks connectedto the ends of said spring and inclosed within said heads, and an exten'10o with chain-links, and an extensible stay connected to said heads,substantially as described.

In testimony that I claim the foregoing as my I 5 invention I havesigned my name in presence of two subscribing witnesses.

HENRY H; KELLY.
